Abstract

Optogenetics provides the sub ms neuronal activity and with single neuron control and sub ms precision this technique already proved its potential for various medical applications. Optically control neuromorphic computing is important on the parameters of Scalability, energy efficiency and frequency of information processing. Optogenetic Switching provides neuronal inhibition, activation, bi-stable, bi-directional and two-photon optical control of neuronal signaling individually and also in a network. In this Paper, we are presenting the single spike and neuronal firing study of optogenetic switching. Here vf-Chrimson expressing Interneuron model has been used to study the irradiance effect on neuronal spike. By the single spiking on/off switching has been used to design the two input simple logic gates by setting threshold irradiance at 1.2 mW/mm². Optogenetic based computing circuits are able to provide better scalability, tunability and temperature stability.
